启动Wildfly（JBoss）服务器时出现VM错误

Question

I have wildfly-10.0.0.Final available with PATH variable set. I am using Ubuntu. Also I have jdk1.7.0_79. I am facing the problem that as when I am trying to start server that is executing standalone.sh then I am getting the error,

Unrecognized VM option 'MetaspaceSize=96M' Error: Could not create the Java Virtual Machine. Error: A fatal exception has occurred. Program will exit.

Answer 1

Use jdk 1.8 instead of jdk 1.7. MetaspaceSize is a new flag added for Metaspace in jdk 1.8.

Answer 2

Check java -version. If it is not java version "1.8.0_xx" , then set the JAVA_HOME environment variable as below and run the command,

bash-4.1$ export JAVA_HOME=LOCATION_TO_JDK1.8.0

Answer 3

您必须在standalone.bat文件中放入此行设置JAVA_HOME = C：\\ Program Files \\ Java \\ jdk-9.0.4，并更改JDK安装的用途。
